python, newspaper,unhashable type: 'tzutc' and writing to dataframe

Question

I have a bunch of urls that I want to download the text and do some further analysis. I am a python newbie. I have two problems: (1) I have a really weird type error; and (2) the results are not being written to the data frame. My code is as follows:

smallURL= ['http://www.walesonline.co.uk/business/business-news/more-70-jobs-created-bio-12836127','http://economictimes.indiatimes.com/articleshow/61006825.cms?utm_source=contentofinterest&utm_medium=text&utm_campaign=cppst','http://100seguro.com.ar/telefonica-pone-en-venta-su-aseguradora-antares-vida/','http://13wham.com/news/local/urmc-opens-newest-urgent-care-facility']

import pandas
import datetime


f = open('myfile', 'w')

#lista= ['http://www.walesonline.co.uk/business/business-news/more-70-jobs-created-bio-12836127','http://economictimes.indiatimes.com/articleshow/61006825.cms?utm_source=contentofinterest&utm_medium=text&utm_campaign=cppst','http://100seguro.com.ar/telefonica-pone-en-venta-su-aseguradora-antares-vida/','http://13wham.com/news/local/urmc-opens-newest-urgent-care-facility']

df = pandas.DataFrame(columns=('d', 'datetime', 'title', 'text','keywords', 'url'))

from newspaper import Article 

for index in range(len(smallURL)):

#url = "https://www.bloomberg.com/news/articles/2017-11-10/microsoft-and-google-turn-to-ai-to-catch-amazon-in-the-cloud"
    article = Article(smallURL[index])
#1 . Download the article
    #try:
    article.download()
    #f.write('article.title+\n')
    #except:
    #pass
#2. Parse the article
    try:
        article.parse()
        f.write('article.title+\n')
    except:
        pass
#Print article title
    #print(article.title)
    article.title
#3. Fetch Author Name(s)
    print(article.authors)
#4. Fetch Publication Date
    if article.publish_date is None:
        d = datetime.datetime.now().date()
    else:
        d = article.publish_date
#5. Print article text
    print(article.text)
#6. Natural Language Processing on Article to fetch Keywords
    #article.nlp()
    #Print Keywords
    print(article.keywords)
#7. Generate Summary of the article
    #print(article.url)
    print(article.url)
    df.loc[index]  = [d, datetime.datetime.now().date(), article.title, article.text,article.keywords,article.url]

My output includes:

TypeError: unhashable type: 'tzutc'

Any idea on what is going wrong and how I can fix it? Thank you!!
